| Abstract: |
| Lignin as a renewable aromatic polymer， is an ideal biomass material for constructing functional hydrogels due to its three-dimensional network structure and abundance of functional groups. This work introduced the structure and sources of lignin， then systematically summarized recent advances in the preparation of lignin-based hydrogels via strategies such as chemical cross-linking and physical assembly， with a particular focus on the regulatory mechanisms of the structure of lignin on the mechanical properties， stimuli-responsiveness， and functional characteristics of the resulting hydrogels. Simultaneously， it provided the comprehensive overview of the applications of lignin-based hydrogels in various fields， including biomedicine， environmental remediation， and flexible electronics. Finally， based on the challenge of controllability in material properties posed by the molecular heterogeneity of lignin， this work offered perspectives on the future of precise structural design and green， scalable production of lignin-based hydrogels. |
